Title: Clipping and inserting device
Inventor: YAGATA SUMITOSHI
IPC: H03H9/10
Filed: 1985-02-07
Abstract: PURPOSE:To reduce remarkably man-hour and to decrease defective piece such as crack or chipping by clipping the piece made of a material such as piezoelectric ceramic between both elastic supports and completing insertion/positioning with one insertion. CONSTITUTION:The piezoelectric ceramic 12 is clipped between both the elastic supports 17, 18 and a contact part 19. Then the piezoelectric ceramic 12 is inserted vertically between the electrodes 9, 10 inserted to a case 11. In inserting the ceramic 12 while spreading the electrodes 9, 10 at the tip of the elastic supports 17, 18 in this case, since the size between the outer side faces of the elastic supports 17, 18 is made coincident with the inner diameter of the case 11, the piezoelectric ceramic 12 is positioned at the center of the electrodes 9, 10 at the same time as the insertion. The insertion is finished when stopper steps 22, 23 of both the elastic supports 17, 18 contact the open ridge of the case 11 and then the ceramic 12 cannot be inserted any more. The assembling and positioning are attained at the same time by one insertion process in this way. Since the piezoelectric ceramic 12 is pressed and held by the electrodes 9, 10 after the insertion, the piezoelectric ceramic 12 is not shifted even when the elastic supports 17, 18 are drawn out.

Title: Paper sheet discriminating device
Inventor: KAWAHITO KATSUHIKO
IPC: G07D7/20
Filed: 1995-01-18
Abstract: PURPOSE: To easily calculate similarity and to shorten processing time. CONSTITUTION: The total number of picture elements in reference data for discrimination is set up to 40×18=720, and with respect to all sorts of paper sheets, the number of picture elements of '1' e.g. is set up to 100 picture elements. Namely patterns are mutually different in accordance with the sorts of paper sheets, and when respective patterns are binarized by the same threshold, the numbers of picture elements of '1' are different in accordance with the sorts of paper sheets. However the numbers of picture elements of each sort can be equalized to be 100 picture elements by adjusting the threshold in accordance with the sorts of paper sheets.  When a paper sheet 3 to be discriminated is read out by a CCD sensor 5, similarity with the reference data is calculated by finding out the number of picture elements of '1' in the reference data superposed with picture elements of '1' in the paper sheet 3 in a product sum computing element 14. When the data of the paper sheet 3 completely coincide with the reference data, the number of picture elements becomes '100', and when both data do not completely match with each other, similarity of '100' to '0' can simply be found out in accordance with the number of superposed picture elements.

Title: Process controller
Inventor: SHIMODA KATSUHIKO
IPC: G05B11/36
Filed: 1984-02-10
Abstract: PURPOSE:To improve the control efficiency and to prevent hunting for switching operation by adding mutual control functions between two, positive-direction and negative-direction PID operations and setting a hysteresis to master/slave switching of the control output. CONSTITUTION:A deviation (e) between a room temperature PV and a set temperature SP is operated in a deviation operating part 1; and if request discrimination of integral terma compensating operation results in affirmation in a positive-direction or negative-direction operation request discriminating part 5A or 5B, a positive-direction PID operating part 2' performs integral term compensating operation and PID operation on a basis of the deviation (e), and a negative-direction PID operating part 4' performs integral term compensating operation and PID operation on a basis of a value obtained by inverting the deviation (e) in a deviation inverting part 3. If request discrimination results in denial in discriminating part 5A and 5B, operating parts 2' and 4' perform only PID operation. When an output limit command is issued, positive-direction and negative-direction output limiting parts 6 and 7 use output lower limit values MLP and MLM as outputs MVP and MVM; but when the output limit command is released, parts 6 and 7 use outputs MCP and MCM of operating parts 2' and 4' as outputs MVP and MVM. If the output of each operating part is smaller than the value obtained by subtracting a hysteresis quantity from the lower limit value, master/slave switching is performed by a master/slave switching part 5E.

Filed: 1980-02-27
Abstract: PURPOSE:To reduce a readout access time by the time as much as required for check bit formation by selecting different start signals by controlling the gate of a signal selecting circuit according to read-write signals. CONSTITUTION:At the reading-out, the AND gate of a signal selecting circuit 20 is opened by the read-write signal 112 from a CPU1. Thereby, the start signal 113 generated at a period earlier by a check bit forming period than the start signal 114 at the writing generated by a timing circuit 30 based on the address request signal from the CPU is selected and is applied to a memory 2. Hence, the readout access time is reduced by the time as much as the check bit formation period than the write access time, and as compared to the case when the writing and reading are controlled by the same start signal, the readout efficiency improves.

Abstract: PROBLEM TO BE SOLVED: To satisfactorily maintain the response signal reception performance of an interrogator by emitting residual vibration energy at the time of every stop of serial resonance, when an interrogation signal is transmitted and stopping the emission before the next time of serial resonance each time. SOLUTION: A control circuit 3 generates a control signal, while an interrogation signal is transmitted and sends in to a transmission circuit 1 and a switching circuit 51. Every time the resonant state of an antenna coil 1 and a condenser 2 is shifted from serial resonance to parallel resonance, the cathode of a diode 51b of the circuit 51 is connected to the ground. With this, a common terminal 1a of the coil 1 and the condenser 2 is connected to the ground. because of this, resonance vibration energy that is accumulated in a resonant circuit of the coil 1, and the condenser 21 is rapidly emitted to the ground immediately before the stop of each serial resonance, and the resonance voltage of the terminal 1a rapidly falls to the forward voltage of the diode 51.  The circuit 3 generates a control signal while a response signal is received, and maintains the resonance state of the coil 1 and the condenser 2 in parallel resonance.

Title: Misfired cylinder discriminating device for multi-cylinder internal combustion engine
Inventor: KASHIWANUMA NOBUAKI
IPC: F02B3/06
Filed: 1991-02-19
Abstract: PURPOSE:To exactly detect a misfired cylinder in a multi-cylinder internal combustion engine. CONSTITUTION:Rotors with an external tooth are fixed to crankshafts, and crank angle sensors are arranged opposite to the teeth of the rotors to determine the crankshaft-angular velocity of each cylinder in the explosion stroke. In this case, when the order of ignition is 1-3-4-2, the crankshaft-angular velocities of the first cylinder #1 and the fourth cylinder #4 are calculated from output pulses generated by the external teeth in the same area I, and for the third cylinder #3 and the second cylinder #2, the crankshaft-angular velocities are calculated from output pulses generated by the external teeth in the same area II. Thus, even when there is a manufacturing error in the projected tooth, for example, in the area II, the crankshaft-angular velocities of the first cylinder #1 and the fourth cylinder #4 are the same unless misfire occurs. But, when the first cylinder #1 misfires, the crankshaft-angular velocity of the first cylinder #1 in the explosion stroke is retarded compared with the crankshaft-angular velocity of the fourth cylinder #4, and thereby misfire of the first cylinder #1 can be detected.
